淺層氣浮與傳統(tǒng)氣浮裝置的比較

① 傳統(tǒng)氣浮裝置中，池深一般為2.0～2.5 m，這是因?yàn)樵O(shè)備是靜止的，水體是運(yùn)動的。水體從反應(yīng)室進(jìn)入接觸區(qū)時會產(chǎn)生流向的改變和流速的重新分布，即把水流轉(zhuǎn)變成均勻向上的流動，這就需要有一定的時間和高度來完成這一變化，其高度一般不低于1.5 m。而淺層氣浮由于“零速度”原理的應(yīng)用，實(shí)現(xiàn)了設(shè)備是運(yùn)動的，水體是靜止的，消除了由于水體的擾動對懸浮顆粒與水分離的影響，降低了對高度的要求；另外在傳統(tǒng)氣浮裝置中，難免有泥砂或絮粒沉于池底，為防止帶出池底的泥砂，出水管一般懸高300 mm，而在淺層氣浮裝置中，由于池底設(shè)置了刮泥裝置，因此不需設(shè)置懸高段。通過以上分析，淺層氣浮裝置的有效水深一般為400～500 mm。
  ② 傳統(tǒng)氣浮裝置中，水體的停留時間一般控制在10～20 min；而淺層氣浮裝置中，停留時間只需2～3 min。
  ③傳統(tǒng)氣浮裝置中，溶氣系統(tǒng)配備的是溶氣罐，若按溶氣罐的實(shí)際容積來計算，其水力停留時間為2～4 min；而淺層氣浮裝置中，溶氣系統(tǒng)采用的是溶氣管，取消了填料，使溶氣管的容積利用率達(dá)100%，其水力停留時間只有10～15 s。
  ④ 在傳統(tǒng)氣浮裝置中，刮渣器定期對浮渣層進(jìn)行清除，無法根據(jù)浮渣的浮起時間進(jìn)行有選擇性的清理，因此不但對水體有較大的擾動，而且浮渣的含水率也較大；在淺層氣浮裝置中，螺旋撇渣器安裝在配水系統(tǒng)的前部，清除的浮渣總是氣浮池內(nèi)浮起時間最長(2～3 min)的浮渣，即固液分離最徹底、含水率最小的浮渣。

（3）Structure and its working principle

Air-floated separation technology is a very good way of purifying water from suspend solid by releasing pressed saturated air water to make its generated air micro bubble contacting with suspended floc fully, which will form flotation sludge to be scrapped out of water by its scrapper .

  Our device is an advanced quick-speed floatation system with all flocculation , floatation, skimming , mud scrapping together under successful use of the "shallow theory" and the "principle of zero speed" to gain high efficiency.

  In order to make up shortcomings of the traditional unit, we design raw water inlet and purified water outlet as movable to save bubble floating time of raw water, namely, while raw water is flowing into the tank, the pool pipe water flow opposite way to make raw water in the pool nearly in static condition , by this way, the bubble can float to the surface quickly like SS flotation speed (4-10 minutes) , meanwhile , the purified water can be drained out when its pipe move here. Due to its compact round design with inlet and outlet pipes installed on rotating rack to generate centripetal moving with nearly zero speed , which will make the suspended solid fast floats on original water surface and then been purified within 3 minutes .

   This equipment is cylindrical and compact in structure, including flotation tank, rotating water distributor, dissolved air release system, rotating rack, water collection device, scum skimmer, dissolved air system, reflux pipe, electric cabinet and etc. Inlet, outlet and sludge discharge outlet are all installed on the rotating area where water distributor, water collection device, dissolved air release system are connected to frame closely, rotating around the flotation tank center.This device provides module integrated equipment assembly by adopting both centralized and decentralized control system to realize the best operating condition.
